For the daily positions of HMS Solent during this patrol see the map below.

18 Apr 1945HMS Solent (Lt.Cdr. J.D. Martin, DSC, RN) and HMS Sleuth (Lt. K.H. Martin, RN) arrive at Exmouth Bay to fuel. Both submarines departed in company for their patrol area later the same day. (10)

23 Apr 1945HMS Solent (Lt.Cdr. J.D. Martin, DSC, RN) torpedoed and sank a small Japanese merchant vessel or large coaster with a torpedo to the South of Bali, Netherlands East Indies in position 08°53'S, 115°04'E.

(All times are zone -9)
0824 hours - Sighted a laden merchant vessel thought to be of about 1300 tons escorted by a large fast looking whaler type escort vessel approaching from the Eastward. Started attack.

0857 hours - Fired a salvo of 5 torpedoes from 2000 yards. Went deep on firing. One loud explosion was heard. This was followed by four more explosions which were most likely the other torpedoes hitting the shore. One of the torpedoes circled overhead twice.

0906 hours - The escort commenced a counter attack which laster for just over one hour. 24 Depth charges were dropped and these were fairly close at first.

1019 hours - Returned to periscope depth. Only saw the escort 5000 yards astern. The target was not sighted. Also one aircraft was seen to be patrolling the area. Went deep again to reload and retired from the area. (10)

1857 hours - Incorrectly judged the ships to be a coaster and a seatruck. Passed this information by SS/T to Sleuth.

1900 hours - Passed to Sleuth 'stand by for gun action'. It was the intention to let the vessels get halfway between both submarines and the engage the larger one together. As it was thought no escort was present there were no restrictions on the use of SS/T.

1918 hours - Went deep to allow the ships to pass overhead. Sent to Sleuth 'enemy is passing me now' The larger vessel now turned out to be an escort vessel and must have head the transmission which was on full power.

1922 hours - A total of 7 depth charges was dropped fairly close in about 10 minutes. Solent went deep as the enemy appeared to be in contact.

1954 hours - The enemy escort had left the scene and as it was dark sent to Sleuth 'surface and close'.

1957 hours - Surfaced and commenced trailing the enemy.

2030 hours - Sleuth joined company and took station 400 yards on Solents port beam. Spent the next two hours manouvering in a position down moon from the enemy and then opened fire with the 4" gun. Fall of shit was difficult to observe as Sleuth was also firing. The enemy replied with 3" and Oerlikon gunfire. After about 15 minutes the escort was hit about 10 times by Solent en Sleuth and ceased firing. She turned towards at speed and was seen to be on fire aft. The enemy passed down Solent's port side at a range of 100 yards when she was riddled with Oerlikon fire at point blank range. Solent then set off in chase of the landing barge that was escorted by this ship. The barge made for Kalambau Island and was soon lost in the shadow of this island. Solent then returned to the escort which was still afloat. Fire was then opened again with the Oerlikon at the centre and fore part.

2245 hours - The escort blew up with a tremendous explosion and a shower of debris landed on Solent. A search was then started to find the landing barge off Kalambau Island.

2252 hours - When Solent was about 900 yards from the shore and was searching the area with her Aldis light she was straddled by a fierce burst of machine gun fire. The barge however could not be seen.

2355 hours - Sighted a ship approaching from the North-East. Sleuth engaged this ship with her 4" gun. Very shortly afterwards Solent was straddled with 3" and Oerlikon gunfire. As the capabilities of this newcomer were unknown it was decided to retire from the scene. Ordered Sleuth to disengage and join Solent.

0121 hours - Sleuth reported that she had obtained 4 hits on the target. Decided to re-engage and both submarines turned round. Searched the North coast of the island and the sea about 5 nautical miles beyond but no sign of her was found. Decided to patrol off the Island during the night to prevent the landing barge from leaving.

0647 hours - Both submarines dived and closed the island to search for the landing barge.

0721 hours - Sighted the landing barge close inshore. Surfaced and closed to 300 yards. Sank the landing barge with 7 rounds of 4" and a pan of Oerlikon. Whilst withdrawing and about 400 yards from the shore sighted a Japanese swimming in the water hanging on to wreckage. Closed and he gratefully scrambled on board. He was a survivor of the escort sunk the day before and he had been in the water for about 10 hours. (10)

1520 hours - Identified the target as a seatruck. Told Sleuth by SS/T to stand by for gun action.

1601 hours - Signalled to Sleuth 'surface and engage'.

1602 hours - Surfaced. Range that was thought to be 2000 yards turned out to be about 4000 yards. The target increased to full speed and started zig-zagging. A hit from Sleuth destroyed her rear machine gun. The forward machine gun of the target could not be brought to bear. This machine gun was soon also knocked out by gunfire.

1620 hours - The target was well on fire but was still proceeding at about 8 knots. Sleuth then closed and fired 4" shells into her waterline but she still would not sink. A lot of men were seen to jump overboard thought to be Japanese soldiers. Upon passing one of them it was seen that he was Malay and soon it was seen that there was a grat number of them including women and children. Both submarines then started to pick up the survivors.

1824 hours - An aircraft was seen to be approaching so both submarines dived. By this time about 90 survivors had been picked up, several were wounded.

1956 hours - Surfaced and proceeded towards the Laurot Islands in the hope of finding a native fishing vessel to get rid of most of the survivors. A prau was sighted and it took off the survivors from Sleuth. Another prau was then sighted and this one took off the survivors from Solent. 4 Trips to the island were needed. By 0130 hours next morning all survivors were landed except 4 Malays who volunteered to remain on board. Many more also would have liked to do so but there was no room for them. (10)

2 May 1945HMS Sleuth (Lt. K.H. Martin, RN) sank an enemy seatruck with gunfire. She was assisted by HMS Solent (Lt.Cdr. J.D. Martin, DSC, RN) which also obtained one hit on the target. Position was 04°33'S, 115°31'E.

0745 hours - The enemy was sighted by Solent, it was a deeply laden coaster of about 300 tons. Both submarines closed at speed. As Sleuth was closer she was ordered to assume tactical command.

0809 hours - Surfaced but as Solent was still 7000 yards from the target did not open fire. Sleuth was much closed and after having fired 4 rounds she hit the target forward starting a small fire which started spreading as other rounds hit. Solent then opened fire from 5500 yards. 3 Rounds were fired for 1 hit but by this time the target was fully on fire. The vessel was seen to burn until 1600 hours when she sank. (10)

17 Jun 1945HMS Solent (Lt.Cdr. J.D. Martin, DSC, RN) departed Subic Bay for her 3rd war patrol (2nd in the South-East Pacific area). She was ordered to patrol together with HMS Sleuth (Lt. K.H. Martin, RN) off Banka Strait and to the East of Singapore.
